It's funny, I had the exact opposite worry. With a rated life of 25 years, the WiFi components are likely to become obsolete long before the bulb itself quits. If I buy one of these, am I going to end up maintaining an obsolete WiFi network in the 2030s just to run my household lights?
The bulbs communicate with their master bulb using 802.15.4, so you'd just need one replacement master that supports whatever new wifi standard emerges. Of course the company itself also needs to still exist in 25 years...
